How can I find alert-type dialogs that prevent other windows of the same application to be focussed?

Here's the problem:

• I just finished burning a CD using the standard feature through Finder, I could hear the "done" sound.


• At that time, I had a different application focussed (e.g. Chrome).


• An alert-like dialog window must have popped up somewhere (e.g. to tell me it's done or something), but I can't find it.


• I now can't focus my already opened Finder window, or even my desktop! I actually can't click any file on my desktop. It will give the short "You can't do that"-sound, kind of a "Bloonk".

I have tried:

• Hiding all windows (of all apps).


• I ejected the CD, thinking maybe the dialog would close then, but it didn't.


• Right-clicking the Finder icon on the dock, to see if the alert dialog is listed, but it's not, and again the only remaining window is not clickable:


• Checking the Expose and moving all windows, no success.


• "Show/Hide Desktop" trackpad gestures in the hope the dialog would pop up.

I have not yet tried logging out or rebooting my computer, I've got tons of project stuff open and I'd prefer not to have to do that. Besides that, this is a childish problem that I shouldn't have to lose to.

How do I find this pesky little dialog? Where is it at? Any help is greatly appreciated.
